However, in the conventional drill screw grinding device, since the main cutting blade of the drill screw is ground to the circumferential surface of the polishing wheel using the grinding wheel, the thinning surface forming the main cutting blade is not formed in a flat plane but is formed in a curved shape. When the two grinding machines polish two thinning faces formed on the drill screw, care must be taken in the arrangement so that the two grinding machines do not interfere with each other because of the large diameter of the grinding wheel. The disadvantage is that it is difficult to precisely adjust.

Therefore, an object of the present invention is to form a grinding wheel in a cylindrical shape, by using a plane located on the opposite side of the surface connected to the connecting rod as a grinding surface, it is possible to sharply grind the main cutting edge of the drill screw, It is possible to grind the thinning face (thinning face) is formed in a flat plane, to provide a drill screw grinding device that can precisely adjust the thinning angle of the thinning surface.

Another object of the present invention is to insert a bearing into the movable member of the stopper to determine the position of the drill screw, so that when the drill screw is positioned by the movable member of the stopper, the leading edge of the drill screw is introduced into the hollow portion of the bearing When the tip of the drill screw is worn out to prevent dullness, and when the position of the drill screw is determined, the movable member of the stopper means returns to the standby position after retreat, whereby the tip of the drill screw is worn by the stopper and blunted. To provide a drill screw grinding device that can be prevented.

The present invention for achieving the above object is a jig for fixing the drill screw, a supply device for supplying the drill screw nail to the jig, and when the drill screw is supplied to the jig by the supply device, the arrangement position of the drill screw nail In a drill screw grinding device comprising a stopper for determining and a cutting edge of a drill mar nail fixed by a jig, wherein the grinding wheel of the grinding machine is formed in a cylindrical shape, a connecting rod is formed at one end of the grinding wheel, and the other end. Diamond powder (or borazone powder) is electrodeposited on the grinding surface so that a plane can be used as the grinding surface.

The grinding machine is connected to the rotary shaft by the connector of the grinding wheel, the rotary shaft is rotatably mounted on the bearing housing, the bearing housing is fixed to the vertical portion of the support plate of the "b" shape, the horizontal portion of the support plate Is mounted on the motor, the power of the motor is transmitted to the rotating shaft by the belt, the support plate is mounted on the forward and backward means, the forward and backward means are arranged on the guide panel, and the forward and backward means is along the rail of the guide panel in the X axis direction. It is forward and backward, the guide panel is mounted on the base panel, it is characterized in that the base panel is mounted on a fixed plate fixed to the work table.

The support plate may be disposed to be inclined with respect to the Z-axis direction, such that the angle adjusting plate is disposed between the vertical portion and the bracket of the forward and backward means, such that the vertical portion is disposed to be inclined to one side relative to the angle adjusting plate. And the angle adjusting plate is coupled by a bolt, and the bolt fixed to one side of the rear side of the angle adjusting plate is fixed by a nut in a state of being inserted into a long groove formed up and down on the front panel of the bracket, so that the height of the angle adjusting plate is placed on the front panel of the bracket. It is characterized in that it can be adjusted relative to.

The present invention also provides a jig for fixing a drill screw, a supply device for supplying a drill screw to the jig, a stopper for determining the arrangement position of the drill screw when the drill screw is supplied to the jig by the supply device, and a jig. In the drill screw grinding device consisting of a grinding machine for the cutting edge of the drill hammer nail fixed by,

The stopper is connected to the connecting rod of the first cylinder to the movable member fitted with the slider, the connecting rod of the second cylinder is connected to the slider, the second cylinder mounted on the fixed frame is disposed at a right angle with respect to the first cylinder, The movable part of the hinge mounted on the connecting rod of the first cylinder is coupled by the fixing part of the hinge fixed to the frame and the pin, and a bearing is inserted into the side of the front end of the movable member.

As a result, the drill screw grinding device according to the present invention can sharply grind the main cutting edge of the drill screw, and can grind the thinning face on which the main cutting edge is formed to a flat plane, and the thinning surface. The angle of thinning can be precisely adjusted, and the stopper has the effect of preventing the tip edge of the drill screw from being worn and dull.
